Abstract: A multiple access, spread-spectrum communication system processes a plurality of information signals received by a Radio Carrier Station (RCS) over telecommunication lines for simultaneous transmission over a radio frequency (RF) channel as a code-division-multiplexed (CDM) signal to a group of Subscriber Units (SUs). The RCS receives a call request signal that corresponds to a telecommunication line information signal, and a user identification signal that identifies a user to receive the call. The RCS includes a plurality of Code Division Multiple Access (CDMA) modems, one of which provides a global pilot code signal. The modems provide message code signals synchronized to the global pilot signal. Each modem combines an information signal with a message code signal to provide a CDM processed signal. The RCS includes a system channel controller coupled to receive a remote call. An RF transmitter is connected to all of the modems to combine the CDM processed signals with the global pilot code signal to generate a CDM signal. The RF transmitter also modulates a carrier signal with the CDM signal and transmits the modulated carrier signal through an RF communication channel to the SUs. Each SU includes a CDMA modem which is also synchronized to the global pilot signal. The CDMA modem despreads the CDM signal and provides a despread information signal to the user. The system includes a closed loop power control system for maintaining a minimum system transmit power level for the RCS and the SUs, and system capacity management for maintaining a maximum number of active SUs for improved system performance. <IMAGE>

Abstract: 1,230,149. Automatic control of viscosity and temperature. TEXACO DEVELOPMENT CORP. Dec. 30, 1968 [Jan. 11, 1968], No. 61614/68. Heading G3R. Solvent refining of oil (in a vessel 13) is automatically controlled by a system in which the viscosity index of the refined oil (raffinate) is measured before the oil enters storage containers 37, 38 and the measured value, together with a target value, are used in a computation of an error signal which is then reduced by adjustment of a variable of the process affecting the viscosity index. The viscosity is determined at 41 by measurement of its refractive index in a side stream 35, 43 of the main flow to storage containers 37, 38 and the value fed to a computer 36. This includes an integrating stage and a desired value input to produce a signal which represents the viscosity error averaged over the contents of a storage container, and is used to control the proportionate flows of solvent S2 and charge S1 and the bottom temperature of the vessel 13 measured by resistance thermometer or thermocouple at 50. If there is a recirculating stage 60 its flow is also controlled by the computer. The computer may be of digital Fig. 2 (not shown) or analogue Fig. 3 (not shown) form. If digital, a number of alternative arrangements are described, some of which require a measurement of raffinate flow at 31 while others assume this to be constant; the arrangements differ principally in whether it is the vicosity signal or the error signal which is integrated. In the analogue system it is the error which is integrated, and the flow is determined by the pressure difference across an orifice; this yields the square of the flow so the square root is derived, which is then integrated to give the quantity of raffinate. The proportioning and the temperature controls may be used independently or jointly or successively, the temperature adjustment acting as a fine control when the proportioning is within a given range. The system may operate continuously or at prescribed intervals which are short compared with the time to fill a container. The temperature control loop comprises a side stream 26, 28 which circulates through a heat exchanger for heating or cooling, the flow of heat exchanger fluid being regulated by a valve 27 controlled by the computer, which effectively determines the reference value for this loop.
